This article shows how and why particular higher education?industry research and development networks articulate with the South African telecommunications sector. The range of competing and complementary data telecommunications technologies available in the South African market provide varying opportunities for enterprises to engage in R&D. Two case studies based in the South African telecommunications industry examine R&D interaction between industry and higher education institutions which have nascent rather than developed R&D capacity and which are dependent on industry initiatives. The analysis suggests that the origin of a particular industry?higher education R&D network is contingent on the growth trajectory of the industrial sector in which it is located and on the maturation of research capacity in the higher education sector with which it is linked.
